Abstract
The utility model discloses a bolt for a crane, and the bolt comprises a screw and a screw cap, wherein threads are arranged on the screw, the screw cap comprises a screw cap body and a lug boss formed on the bottom part of the screw cap body and protruding from the screw cap body, and the bottom surface of the lug boss and the connecting surface of the screw cap body and the screw are located on the same plane. When the bolt for crane disclosed by the utility model is in use, the added lug boss increases the contact area of the screw cap and the equipment to be fixed to increase the friction force so as to prevent the bolt from easily loosening or dropping, so that the locking effect is better to guarantee the normal operation of the equipment, and the potential safety hazard is reduced as a result.
Description
Technical field
The utility model relates to a kind of bolt, particularly a kind of bolt that is used for hoist.
Background technique
At present, the existing bolt that is used for hoist includes screw rod and nut, and screw rod is provided with screw thread; Nut is a cylindrical body, and the nut top is provided with the spanner screens, when the bolt of this kind structure uses; Nut with treat that the area of contact of fixed equipment is little, frictional force is little, so bolt moves back pine easily even comes off; Locking effect is relatively poor, thereby the equipment that possibly influence normally moves, and constitutes potential safety hazard.
The model utility content
The main purpose of the utility model is the shortcoming that overcomes existing technology, and a kind of bolt that is used for hoist that can be effectively locking is provided.
The utility model adopts following technological scheme:
A kind of bolt that is used for hoist; Include screw rod and nut; Said screw rod is provided with screw thread, and said nut includes the nut body and is formed at the boss that one of nut body bottom protrudes from the nut body, and the junction surface of this boss bottom surface and nut body and screw rod is in the same plane.
Said nut body is a cylindrical body, and said boss is the thin wall circular that connects as one with the nut body that is formed at nut body bottom.
Said nut bodies top is provided with the hex wrench screens of an indent.
Can know that by above-mentioned description compared with prior art, the beneficial effect of the utility model is: during use to the utility model; The boss of setting up has increased nut and the area of contact of treating fixed equipment; Increased frictional force, made bolt more be difficult for moving back pine or coming off, locking effect is better; Can guarantee that equipment normally moves, thereby reduce potential safety hazard.
Description of drawings
Fig. 1 is the three-dimensional structure diagram of the utility model embodiment;
Fig. 2 is the sectional structure chart of the utility model embodiment.
Among the figure: 1. screw rod, 10. screw thread, 2. nut, 20. nut bodies, 21. boss, 22. spanner screens.
Embodiment
Below the utility model is done further to describe through embodiment.
See figures.1.and.2; A kind of bolt that is used for hoist of the utility model; Include screw rod 1 and nut 2; Said screw rod 1 is provided with screw thread 10, and said nut 2 includes nut body 20 and is formed at the boss 21 that one of nut body 20 bottoms protrude from nut body 20, and the junction surface of these boss 21 bottom surfaces and nut body 20 and screw rod 1 is in the same plane.Said nut body 20 is a cylindrical body, the thin wall circular that with nut body 20 connect as one of said boss 21 for being formed at nut body 20 bottoms.Said nut body 20 tops are provided with the hex wrench screens 22 of an indent.
See figures.1.and.2, when the utility model used, the boss of setting up 21 had increased nut 2 and the area of contact of treating fixed equipment; Increased frictional force, made bolt more be difficult for moving back pine or coming off, locking effect is better; Can guarantee that equipment normally moves, thereby reduce potential safety hazard.
An above-mentioned embodiment that is merely the utility model, but the design concept of the utility model is not limited thereto allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
Claims (3)
1. bolt that is used for hoist; Include screw rod and nut; Said screw rod is provided with screw thread; It is characterized in that: said nut includes the nut body and is formed at the boss that one of nut body bottom protrudes from the nut body, and the junction surface of this boss bottom surface and nut body and screw rod is in the same plane.
2. a kind of bolt that is used for hoist as claimed in claim 1 is characterized in that: said nut body is a cylindrical body, and said boss is the thin wall circular that connects as one with the nut body that is formed at nut body bottom.
